Exhaust manifold is tough as it is cast iron. Need some pretty tough industrial tools to get that done. Intake manifold is aluminum so I just used a carbide coated metal filer to saw away at the surface.

I use a cutting bit to gasket match and then little sand paper wraps that have a long metal attachment to do down inside the runners. Its pretty darn time consuming.

That is your problem. You were using a bit that is too much for such a soft metal. In the pics you can see that it had a flat end and dug into the metal a lot. It also creates jagged spots. The intake manifold is really soft and not much to remove so sand paper roll bits too the job perfect.
